Hi

I attached a program for a G120, you may need to do some changes to make it work for G110.

Hope this answer was helpful.

You need a PtP Communication module (serial interfaces) . E.g. the ET 200SP module CM PtP (6ES7137-6AA00-0BA0).

You must program a USS Master in the SIMATIC.

Read the general and the USS chapters in this manual:   https://support.industry.siemens.com/cs/ww/en/view/59057093
